玻璃纤维筋在桥梁工程中的设计与应用

Design and Application of Glass Fiber Reinforcement in Bridge Engineering

玻璃纤维筋混凝土在轨道交通围护结构中常有应用,但在桥梁结构中尚不多见。结合上海轨道交通15号线区间穿越张家塘港桥桩基工程,介绍和分析了玻璃纤维筋材料的物理力学性质;利用玻璃纤维筋混凝土桩基替代普通钢筋混凝土桥梁桩基,解决了桥梁基础体系转化时结构承载力问题。这可供类似工程参考。

The glass fiber reinforced concrete is often used in the retaining structure of rail transit projects, but it is still rare in bridge structure. Combined with the pile foundation engineering of the Zhangjiatang Gang Bridge of Shanghai Rail Transit Line 15, it introduces the mechanical properties of glass fiber reinforcement. The pile foundation using glass fiber reinforced concrete in instead of reinforced concrete solves the problem of structural bearing capacity during the transformation of bridge foundation system. This can be used as a reference for similar projects.
